Abstract
An imaging system includes a beam generating system configured to generate a light beam of 0.5 kW or greater with a predetermined intensity profile across at least one axis transverse to a propagation axis thereof and to direct the light beam along a beam path, a light modulator configured to receive the light beam and to modulate the light beam into a predetermined illumination pattern, and an optical relay configured to receive the portion of the light beam and reflectively project the beam to a target, wherein the illumination pattern is imaged at the target with substantially time-invariant spatial accuracies of 500 μm or less in a plane transverse to the propagation axis and 1000 μm or less parallel to the propagation axis.
